TRADE-MARKiNGi MACHINE.

Specification of Letters Patent.

Patented May 2, 11916..

Application filed July 26, 1913. Serial No. 781,295.

To all whom it may concern Be it known that I, JOHN W. HOGUE, citizen of the United States, and resident of Springfield, county of Windsor, State of Vermont, have invented certain new and useful Improvements in Trade-Marking Machines, of which the following is a specification.

This invention relates to machines for stamping or marking with ink, cloth or other fabric and is intended to provide an efiicient and reliable device which may be applied to batching machines or other machines through which the cloth or fabric to be marked is drawn or fed.

In its general features the invention comprises in combination with a marking die or type member, a hollow casing or ink reservoir closed except for a small slot to be traversed by the movable die and having an inking pad arranged in immediate proximity to said slot, in position to form a contact with said die before the die is moved into contact with the fabric to be marked, one object being to prevent the evaporation or drying of the ink. This and other features of the invention will be particularly described in the following specification, and will be defined in the claims annexed hereto.

In the accompanying drawings I have illustrated the preferred mode of embodying the principles of this invention. 7

Figure 1 is a side elevation of the trademarking device shown applied to so much of a batching machine as is necessary to understand the operation of the invention; Fig. 2 is a front elevation of the same; Fig.

3 is a central vertical section through the ink reservoir and its inking members; and Fig. 4 is a transverse vertical section on the plane indicated by broken line 1-4 of Fig. 3.

In practice this machine is made in the form of a removable. attachment that may be applied to various kinds of machines through which the fabric to be stamped is usually passed, such for example as a batching or cloth rolling machine. In this connection I have shown merely the cloth feed ing roll a and a portion of the framework a of such a batching machine adjacent to the point wherethe trade-marking mechanism is attached.

The trade-marking mechanism embraces amovable and preferably a revolving die or type member I), which is detachably secured to a revolving gear 6' which is driven from the gear a of the cloth roll a, or by any suitable means that coordinates the movement of the die I) with the travel of the cloth so that the die may be brought into contact, preferably a rolling contact, wlth the cloth at the same rate of speed as the travel of the cloth, so that the cloth and the die may move in unison during their period of contact. Adjacent to the periphery of. the circle described by the die 6 is arranged the ink reservoir which containsopening at oneend'which is normally closed I by the plate or closure 0 which is held snugly but detachably in position by the retaining bolt 0 The opposite end of the casing is provided with a slot a normally closed by a bracket plate 0 from which projects inwardly a fixed pintle c which forms an adjustable journal for the rotating inkcarrying cylinder 0. This plate or bracket 0 is pivotally clamped to the adjacent end of the ink Well, as indicated at 0 and is adjusted vertically by means of the adjusting screw 0 tapped into the bottom of the shell 0, and engaging a projecting arm of the bracket 0*. v

The ink pad from which the die receives its ink is in the form of a rotary roll d whose supporting end is journaled in a cylindrical bore formed at d in the shell 0. Theinking portion of the roll is preferably encircled with a sleeve or pad d of felt or other suitable ink-retaining material, which is held in place by means of a sort of washer d and end screw 01. At d the roll is formed with gear teeth, which engage gear teeth 0 on the ink-carrying roll, in order to drive the latter roll. The pad roll at itself is driven by a pinion d which intermeshes with the gear I), the parts being so proportioned and arranged that the surface of the pad roll or ink-applying member moves at the same surface speed as that of the die 6, so that the two members may travel in unison while they are in contact."

To avoid the seepage or leakage of ink through the pad roll bearing d, this p0r tion of the pad roll is formed with an an nular groove, as shown at 03 which registers with a slot or opening in the bottom of the bearing, as indicated at d, so that the ink on reaching this point will naturally flow through the opening 03 and fall into the bottom' of the reservoir or shell.

The inkapplyingroll or pad d is set as close as practicable to the periphery of the shell at the side where the die passes by it, the wall of the shell being made very thin at this point and being provided with a short peripheral slot, as shown at (15, through which the die passes at each'revolution. Theink may be applied through a suitable orifice e, which may be closed by a plug or cap. Only the lower portion of the shell is filled with the ink whichis carried by the gear-roll c in a thin film into contact with the pad, which in turn applies the ink directly to the marking die 6. Both internal rolls may be removed or replaced through the large orifice which is normally closed by the plate 0'. The adjustment of the journal 0 serves to give the proper pressure or contact between the two rolls.

The shell 0 is provided withperforated ears or lugs f by which it is detachably secured to a supporting bracket f by suitable fastening bolts, so that the shell may be removed and replaced by another shell when it is desired to change thecolor of the ink or for any other reason.

What I claim is 1. A hollow casing or shell provided with openings at its opposite ends, a removable closure for each opening, one of ,said closures being provided with an inwardly extending pin projecting into the interior of the casing to support an ink-carrying roll, a revolving pad mounted above said roll adjacent to a slot formed in the upper wall of said shell, an external set screw having operative connection with said intle to ad= just the same toward or away rom the pad and means for causing said rolls to rotate in unison, substantially as described.

2. In a machine for trade marking cloth the combination with therevolving cloth roll, a revolving marking diearranged to mark the cloth at each revolution, a closed ink reservoir provided with a revolving inking pad whose periphery 1s exposed to contact with the die at each revolution,

the revolving die through a slot in the reservoir and interconnecting gearing by which the pad, the cloth roll, and the die are rotated at the same surface-speed.

3. In a cloth marking machine the combination of the marking die mounted on a revolving member, a hollow closed ink reservoir arranged adjacent to the circular path of the dies travel and slotted on one side, a revolving inking pad inclosed in said reservoir close to said slot to contact with said die at each revolution thereof, a driving pinion intermeshing with a gear on the revolving member and proportioned to cause the pad to rotate at the same surface speed as the die, an ink supplying roll inclosed 1n the reservoir in contact with said pad, and a pinion secured thereto and intermeshing with the pad pinion to cause said roll and said pinion to rotate positively in unison,

substantially as described.

In a machine for trade marking cloth, the combination with the revolving die, of an ink reservoir slotted-on one side to admit pad inclosed within said reservoir with its surface close to said slot, an ink supplying roll also inclosed within said reservoir to rotate in contact with said pad, and intermeshing pinions secured to the pad and to the roll, respectively, to cause them to rotate positively at the same surface speed substantially as described.

5. An inking device for a cloth marking a rotary inking 4 machine embracing a hollow shell slotted on one side to receive a revolving marking die, a rotary inking pad inclosed within said shell close to said slot in position to contact with the die, an ink supplying roll also inclosed within said shell and having a positive gearlng connection with said pad to cause its rotation in unison therewith, and adjusting means by which the pressure of contact between the ink roll and the varied, substantially as described.

In witness whereof, I have subscribed the above specification.
